Effective conservation of endangered species requires knowledge of the full range of life-
history strategies used to maximize population resilience within a stochastic and ever …

In estuaries, fluctuating environmental conditions exact strenuous physiological demands on
the fishes that inhabit these oft-impacted areas, including the Critically Endangered delta …

The movement responses of juvenile fishes exposed to intermittent hypoxia mediate the
effects of impaired water quality on estuarine nursery habitat function. Twenty-five juvenile …

The Delta Smelt is a largely zooplanktivorous, endangered fish endemic to the San
Francisco Estuary (the estuary). High flows increase the availability of fresh and brackish …

Climate change may cause organisms to seek thermal refuge from rising temperatures,
either by shifting their ranges or seeking microrefugia within their existing ranges. We …

Many river systems within the Central Valley of California have been disconnected from their
floodplains, hypothesized to be partially responsible for declining Chinook salmon …

While freshwater inflow has been a major focus of resource management in estuaries,
including the upper San Francisco Estuary, there is a growing interest in using focused flow …

Intentional introductions of non-native fishes can have severe consequences on native
communities. Wakasagi (Hypomesus nipponensis, referred to as Japanese Pond Smelt) are …

Terminal channels were historically a common feature of tidal delta ecosystems but have
become increasingly rare as landscapes have been modified. Tidal hydrodynamics are a …

Correctly identifying the environmental factors that limit population growth and recovery of
imperiled species is an essential element of any targeted conservation program. Abundance …
